Why You Should Exercise Today ... and Every Day
For too many people, the only "exercise" they get is to go from the bed to a car to a desk to a couch, and then back to bed again. And a recent study shows just how harmful this can be.

Researchers at the University of Missouri-Columbia provided a group of rats with exercise wheels. After allowing the rats to exercise every day for three weeks, they locked the wheels - and within only 48 hours, the rats' sensitivity to insulin dropped by one-third. The insulin sensitivity continued to decrease as long as the rats were active.

Why is this important? Because decreased sensitivity to insulin is a precursor for diabetes, heart disease, high blood pressure, and obesity.

Insulin binds with receptors on muscle tissue and creates a path for the glucose in your bloodstream to be transferred into the muscles and other tissues. When you are active, this metabolic process is rapid and efficient. However, when you are sedentary (even for 48 hours), it takes greater and greater amounts of insulin to reduce the glucose in your blood.
